    • Extracting useful information on the image provided by the invention described herein is a new method. It is different from the pure remote sensing supervised classification and unsupervised classification, and also different from the Object-Based (or Object-Oriented) Image Analysis Classification. Its main feature is to quickly select the same sample by pixel, with the sample threshold limit, the ratio calculated for each color channel, the establishment of linear or non-linear characteristics and parameters of the model, and adjustment of deviation control to complete the extraction of useful information quickly. Through the production and experimentation of the software has proven its high efficiency, but also for addressing remote sensing in the isomer spectrum (different spectrum of the same substance), homogeneous stratification problem provides an effective method. In addition, according to the principles and process flow characteristics of the present invention, it is also suitable for various other categories of information extracted image, such as meteorology, medical and other industries, its usage is limitless.

    • Embodiments of the present invention provide a signal processing method and device. The method includes: selecting M sub-bands from N sub-bands, where the N sub-bands are obtained by dividing spectral coefficients of a current frame of a signal, and frequency bands of the M sub-bands are lower than frequency bands of K sub-bands in the N sub-bands except the M sub-bands; determining, according to performance information of the M sub-bands, to perform a modification operation on original envelope values of the M sub-bands, where the performance information is used to indicate an energy characteristic and a spectral characteristic that are of the M sub-bands; performing modification respectively on the original envelope values of the M sub-bands, so as to acquire modified envelope values of the M sub-bands; and performing first bit allocation on the N sub-bands according to the modified envelope values of the M sub-bands and original envelope values of the K sub-bands. In the embodiments of the present invention, bit allocation better meets a bit requirement of each sub-band, and therefore, signal encoding and decoding performance can be improved.
